Title: Improvements in electro-chemical integrator
IPC: G01R22/02
Filed: 1963-05-15
Abstract: 974, 197. Electrolytic meters; measuring electrically. CURTIS INSTRUMENTS Inc. May 15, 1963 [May 24, 1962], No. 19341/63. Headings G1N and G1Q. A coulometer, Fig. 1, comprises a tube 10 of non-conductive material such as glass, ceramic, epoxy resin &c. in a bore 11 of which two liquid metal columns 12, 13, e.g. mercury, extend from opposite ends, being separated by a quantity of electrolyte 14, e.g. an aqueous solution of potassium iodide and mercuric iodide; current to be integrated is passed through the meter via leads 16, 17 which contact columns 12, 13 respectively, causing mercury to be electroplated from one column to the other. The quantity of electricity which has passed through the meter is measured by determining the capacitance between at least one mercury column and a conductor 20 disposed around the tube. In Fig. 3, a fraction of the test current is shunted across a resistor 35, amplified at 36, and supplied via a reversing switch 38 to the mercury columns 12, 13. The output of a H.F. oscillator 40 is also supplied to the mercury columns, the voltage developed on conductor 20 being amplified at 43 detected at 44, and fed to an indicating device 45 which may be calibrated in ampere-hours or time; the D.C. signal from 44 may also be fed to a control relay 46 to actuate an alarm, or effect automatic shut-off of electric power, or reversal of switch 38, when a predetermined quantity of electricity has passed through the meter. Fig. 4 shows a push-pull arrangement in which A.C. is supplied to the mercury columns from the ends of the centre-grounded secondary of a transformer 52. When the mercury columns are of equal length there is no output from conductor 20; otherwise a differential signal is produced which is amplified at 53, phase sense detected at 54, and supplied to a centre-zero indicating instrument 56 and to control relays 57, 58. In a modification, two or more conductive bands around tube 10 replace the single conductor 20.

Title: Photographic camera with an exposure regulating device
IPC: G03B7/085
Filed: 1965-05-07
Abstract: 1,088,915. Exposure control. AGFA A.G. May 7, 1965 [May 15, 1964], No. 19375/65. Heading G2A. A diaphragm setting ring 1 has pins 2 each engaging a control slot 3 of a diaphragm leaf 4 pivoted on a fixed pin 5. The ring 1 is urged counterclockwise by a spring 6. An electrical supply, e.g. a dry battery supplies relay 12 and a photo-resistor 11 positioned behind a honeycomb or converging lens. The photo-resistor can be masked to take account of shutter speed or film sensitivity. A camera release 15 closes a master switch 13 on depression and allows a diaphragm pawl 20 to rock in the clockwise direction to release ring 1 and to close a switch 14. Relay 12 is energized to attract pawl 27 after a delay period depending upon the resistance of photo-resistor 11 to arrest ring 1 by engaging toothed section 32, thus providing a diaphragm setting corresponding to the illumination. A tensioning lever 37 returns to its initial position by engagement with pin 43. In a modification, a slidable spring-urged camera release (55) Fig.2 (not shown) has a projection (62) for actuating release pawl (63) and a projection (54) for engaging a pin 52 to return the diaphragm setting ring (50) to its initial position after an exposure.

Patent GB-1595856-A (GB)
Title: Data processing
IPC: G06F13/42
Filed: 1978-05-15
Abstract: With a memory request of the processor (CPU), a request signal (START) is transferred, after the memory parameters have been defined, to the memory control unit (SPS) of the storage system (SP) where it triggers a memory cycle with its arrival. The memory control unit (SPS) signals the error-free conclusion to the control unit (SE) of the processor (CPU) by means of keying pulses (RDY or, respectively, ACC) of defined length and by this means restarts the clock generator (TG) which was stopped with a delayed conclusion of the memory cycle. This concludes the process by resetting of the static signals at the processor end after the data have been transferred into or out of the memory system. The method can be applied in data processing systems having a number of processors with analogous structure and a common memory system. <IMAGE>

Abstract: 706,006. Winding and unwinding yarns etc.; driving and tensioning regulating. BRADLEY, W. July 20, 1950 [July 26. 1949], No. 19612/49. Class 120(2) [Also in Group XVI] Apparatus for controlling the winding and unwinding of 'flexible material, e.g. yarns, fibres, filaments, bands, tapes, web &c. passing between two carriers 3, 4, includes rollers 6, 7 over which the material passes, driven by a chain-drive 8 which passes over a pulley 8a on a spindle carrying a gear 9 which may be selectively engaged with either of engaged gears 11; 12 which are constantly driven by means of a motor 13. As shown the gear wheel 9 meshes with the gear 12 so that the material is wound on to the carrier 3 and off the carrier. 4. The gear wheels 11, 12 form part of a pair of friction clutches Fig. 2 (not shown), of any known type which are controlled by movement of pivoted bell-crank levers 30. The material passes over guide bars 25 set in position by a lever 28 and linkage 26, 27, and also over feeler bars 24 mounted on the levers 30. These levers are each provided with dashpots 31 and counter-balancing weights 32. In operation should the tension increase both the levers 30 will be rotated so as to raise the weight 32 thereby causing the friction clutches to slip, decreasing the drive on the carrier 3 and decreasing the braking effect on the carrier 4. If the tention decreases the levers 30 move in the direction to increase the drive on the carrier 3 and increase the braking effect on. the carrier 4. The levers 30 are connected together by a rod 29a pivotally connected at one end to one lever 30 and slidable through it connected to the other lever 30 with a spring-loading at 29b between the latter lever connected and an adjusting nut 29c. The levers 30 may then be adjusted towards or away from each other to vary the initial tension.

Abstract: 1515612 Optical projectors with automatic focusing FRANKE & HEIDECKE GmbH 13 May 1976 [16 May 1975] 19731/76 Heading G2J A slide projector in which automatic focusing is accomplished by an electric motor controlled by a circuit including a photo-electric cell, has a changeover switch in the circuit so that the motor may alternately be used when the slide is changed to move the lens to defocus the slide and then return the lens for automatic focusing. As shown, a slide 1 is supported in the image gate, and a sliding plate 2 carries a differential photo-electric cell 5. The output of cell 5 controls, in known manner, a motor 20 which moves a lens 18 to focus slide 1 on a screen. Lens 18 is connected to a slide 11 detachably connected to sliding plate 2. When the slide is to be changed a changeover switch 26 is operated; this energizes motor 20 in a direction to move lens 18 away from slide 1, defocusing it. Sliding plate 2 also moves, and a contact 34 thereon moves over a resistance 35 dimming the projection lamp 38. Eventually a pin 4 on sliding plate 2 operates a limit switch 33 and the lens 20 stops. When the new slide is in position, the automatic focusing circuit brings the lens back, and the lamp 38 returns to full brightness.

Title: Arrangement for the automatic control of a shut-off cock in  an automatic coupling head of a railway vehicle
IPC: B60D1/62
Filed: 1971-04-19
Abstract: 1310459 Controlling air shut-off cocks on railway vehicle couplings COMPAGNIA ITALIANA WESTINGHOUSE FRENI E SEGNALISpA 19 April 1971 [26 Jan 1970] 20019/71 Heading B7T [Also in Division F2] An arrangement for the automatic control of a shut-off cock R in a compressed air supply conduit C.G. associated with an automatic coupling head of a railway vehicle comprises a distributer D having a spool 4, a control cylinder C, a control member A and an isolating device B, the arrangement, when the coupling head is coupled to a similarly equipped head, opening the cock R as follows: the spool 4 is moved to the right, by contact with the spool on the other head, against the centring action of springs 5, 6 thereby causing air from conduit 1 to be supplied via conduits 3 and 9 and space 10 to chamber 8 of cylinder C. The piston 15 is moved to the right against spring 17 and the cock is opened by way of lost motion pin and slot connection 18, 19. As piston 15 passes over orifice 21 air is supplied to the left hand side of piston 22 thereby causing the piston-rod to cut the path of chamber 8 to atmosphere via conduit 12 and port 14. Air is then admitted from conduit 3 via space 10 to conduit 26 and to the right hand side of piston 15 causing it to be recentred but with the cock remaining open and pin 18 to the right of slot 19 to allow for manual closure of the cock. If the vehicle is connected direct to a locomotive the air reaches conduit 3 via conduit 29 and not conduit 1. To uncouple two vehicles a lever 31 is moved to the right supplying air via conduit 34 to space 35 of distributer D. Spool piston 37 moves to the left causing conduit 9 to be vented via ports 11 and 41. The chamber 7 of cylinder C is therefore evacuated and the air pressure in chamber 8 causes piston 15 to move to the left whereby cock R is closed. The spool of the other head is moved by the pressure in space 35 via spool 4 to its extreme outer position and likewise the conduit 9 and chamber 7 thereof is vented causing the cock of the other vehicle to close. After uncoupling lever 31 is released and the arrangement returns to its Fig. 1 condition. In the event of accidental uncoupling of the two vehicles the distributer spools adopt the Fig. 1 condition and air is discharged from the open ends of conduits C.G. The cocks R remain open since both chambers 7 and 8 of the cylinders C are vented to atmosphere. In a modification, Fig. 5 (not shown), the distributer spool is moved during a coupling operation by a sheathed cable connected between the coupling head and the distributer housing.

Title: Improvements in or relating to the heat treatment of gaseous mixtures
IPC: C07C4/02
Filed: 1929-07-01
Abstract: 314,807. Soc. d'Etudes et Realisation dite Ereal. July 2, 1928, [Convention date]. Grant of Patent, opposed. Oil gas.-In a process for treating gaseous mixtures containing a large proportion of gaseous hydrocarbons, e.g. methane &c. and having a small content of hydrogen and carbon dioxide, to dissociate the hydrocarbons into hydrogen and carbon, in which the gaseous mixtures are forced through an incandescent fuel mass, the temperature of the fuel is maintained between 800 and 1200‹ C. substantially by combustion of the separated carbon only. The plant comprises a shaft furnace A provided with a grate B and charging hopper C for introducing the fuel, the furnace A communicating with recuperators DE arranged cyclically round a central recuperator FG. The furnace is filled with coke which is burnt by air admitted through a pipe 1, which circulates round the tubes of the recuperators DE, and passes through a pipe 3 and a jacket 4 to apertures 5 in the bottom of the furnace. The air gas formed passes through the openings 6, pipe 7 and the tubes DE to escape by a pipe 8. The gases to be decomposed are then admitted through a pipe 9 and pass over the tubes FG through a pipe 10 to the bottom of the furnace, while the cracked products escape through the tubes FG and the pipe 11. The cracked gases and the air gas may be mixed together or used separately. Oxygen or water vapour may be used instead of air. In an example, a residual gas from coke manufacture containing about 7 per cent of hydrogen and 73 per cent of gaseous hydrocarbons is converted into a mixture containing 85 per cent of hydrogen. Specifications 271,491 and 286,291, [both in Class 90, Non- metallic elements], are referred to.
